As timers, these 5, monolithic integrated circuits are capable of producing CA555 accurate time delays for periods ranging from microseconds through hours. These devices are also useful for astable C, LM555 oscillator operation and can maintain an accurately controlled free running frequency and duty cycle with only C) two external resistors and one capacitor. /SubThe circuits of the CA555 and CA555C may be triggered by ject the falling edge of the waveform signal, and the output of (Tim- these circuits can source or sink up to a 200mA current or ers for drive TTL circuits. Timing These types are direct replacements for industry types in Delays packages with similar terminal arrangements e.g. SE555 and and NE555, MC1555 and MC1455, respectively. The CA555 Oscilla- type circuits are intended for applications requiring premium electrical performance. The CA555C type circuits are tor Appli- intended for applications requiring less stringent electrical cations characteristics. in Part Number Information ComPART NUMBER TEMP.
